need help making a thermistor table... {I got it... solved]

ok,
I recently purchased extra thermistors from Ultimachine and am having trouble getting the python script to work... mainly because i don't know python or how to use the script... i cant seem to get it to execute properly on my windows machine. I'm not a programmer. so I'm kinda stuck...

so I am hoping that someone would be kind enough to make me a thermistor table, or explain how to use the python script... [svn.reprap.org]

thermistor model:
B57560G0104F

here is the thermistor data-sheet... this thermistor is located on page 36 of this data-sheet...

svn.reprap.org is an old version of the software and should be ignored. The latest version is at http://reprap.svn.sourceforge.net/viewvc/reprap/trunk/reprap/firmware/Arduino/utilities/createTemperatureLookup.py?view=markup&pathrev=3448

MB: Thanks for fixing the Thermistor page on the wiki -- I went to edit it, and you beat me to it

not a problem... cheers

I'm uploading the firmware to my tech zone remix kit, and have this thermistor from ultimachine. It's model number B57560G 104F like MB says above.
But the model on the wiki is B57540G0 104F?
Unfortunately the datasheet from the supplier is not available. So I'm not able to check if the specifications differs, or calculate another one.
Is the model number in the wiki wrong, or can the models use the same table?

The link on the Ultimachine website is now broken!!! It looks like Epcos removed the data-sheet from their site!

It was working a few days after my initial post.




Um, Could someone from UltiMachine please help?

I'm in the same boat, having bought thermistors I am not sure how to use after all.
Maybe I should have verified they were the same first.

I calulated mine manually... [reprap.org] then used the python script...


however i think I'm still around 20C off... (it reads 20C too high)


edit: they should work... we just need to make or find someone with a working table..

edit2: Im thinking about curving the value that i input into python by 20 degrees...

Looks like the path has the year encoded in it and they updated the datasheet breaking everybody's links, cabbages!

Anyone have a working table for the Ultimachine thermister they could share?
Thanks!

Sorry I missed this thread earlier.

I posted our thermistor table to the wiki @ [reprap.org]

Thank you!
